HEATING APPARATUS.

To all whom it may concern Be it known that I, Amsrmn HARRY Dns PAROIS,a British subject, residing at No. 217

Boyer Street, in the city of Montreal, in the Province of Quebec, in theDominion of Canada, have invented certain new and useful Improvements inHeating Apparatus; and I do hereby declare that the following is a full,clear, and exact description of the same.

The present invention relates to improvements in heating apparatus, andits main object is to provide an external casing of any suitablematerial, around a furnace for instance, which will increase its heatingproperties considerably.

A further object is to provide means for supporting the bafiie plates insaid casing and for securing together the sides of said casing.

Another object is to provide in said casing suitable doors adapted toenhance the general appearance of the device.

The invention will be understood with the aid of the followingdescription and accompanying drawing, in which Figure 1 is a frontelevation of the device.

Figure 2 is a vertical sectional side view.

Figure 8 is an enlarged perspective View of a portion of the walls ofthe casing illustrating the means for securing the sides together.

Figure 4 is a perspective view of the securing device.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawing, 1 are the vertical walls of the casing adaptedto enclose the furnace 2. These walls preferably project from the floor3 above the furnace, and 4 is a cover.

In the front of said casing is an open space or vertical chamber 5,which permits reaching the ash, fire box and section doors 6, 7 and 8respectively, and which is preferably closed at its sides and back bythe vertical partitions 9 and 10.

The space 5 is preferably closed in front by the sliding doors 11 and 12which operate in the guideways 13, and on which are mounted the weights14-.

Within said casing, at suitable intervals are disposed horizontalpartitions or baffle plates 15, which completely fill the space providedbetween the walls of the casing Specification of Letters Patent.

and furnace. Each of said partitions is preferably provided with anopening 16. The openings 16 are in Zig-zag arrangement in relation toeach other, in order that the gases and fumes escaping from the smokeoutlet of the furnace will be forced to travel around the furnace walls.A pipe 17 leading to the chimney is connected to the lower section atthe bottom of said casing.

The partitions 15 are held horizontally on the inner walls 1 of thecasing by means of the angle bars 18 which are suitably secured thereto.The meeting ends of said angle bars 18 are adapted to overlap at thecorners of the casing and are provided with registering holes 19 throughwhich projects a clamp 20.

The clamp 20 consists of a wedge shaped member 21 having a horizontalportion 22 which projects through the opening at the corner of thecasing, the wedge engaging the holes 19. Vertically in relation to thehorizontal portion 22 is secured a tubular member 28 which rests againstthe edges of the side walls of said casing and securely locks said wallstogether. A similar clamp is secured at each corner of the casing ineach row of angle bars 18, and 24 is a rod which projects through thetubular members 23 to secure together the clamps at each corner of thecasing.

It will be seen that the casing is readily collapsible by removing therods 24: and knocking out of the holes 19 the clamps 20, should it benecessary to repair or clean the furnace.

The fumes escaping from the smoke outlet of the furnace enter the uppersection, passing through the openings 16 in the partitions and so on,until they reach the lower section at the base of the furnace when theypass through the pipe 17 into the chimney. Thus the hot fumes will forma heating jacket around the furnace walls, slowly circulating throughthe different sections, with the result that when the fumes reach thepipe 17 they are practically cold. The zigzag circulation causes thefumes to remain around the furnace walls, with the result that theefficiency of the furnace is greatly increased. The collapsible casingis also an important feature, as it can be rapidly set up by unskilledhands.

hat I claim as my invention is 1. The combination with a heating furnacehaving a smoke outlet at its upper end, of an exterior casing enclosingsaid furnace and suitably spaced from the walls thereof; verticalpartitions Within the casing defining a space or chamber in front of thedoors of the furnace to provide access to said doors; a plurality ofspaced, horizontal partitions secured in said casing in the spacebetween the walls thereof and the furnace, and dividing said space intoa series of superposed sections, each section having a hole inzigzagrelation to thehole in the adjacent partition; and a pipe leadingto the chimney communicating with the bottom section substantially asdescribed.

2. The combination with a heating furnace having a smoke outlet at itsupper end, of an exterior collapsible casing enclosing said furnace andsuitably spaced from the walls thereof; a plurality of horizontalpartitions forming a series of superposed sections within said casing,said partitions having holes to provide communication between suchsections and a pipe leading to the chimney connnunicating with one ofsaid sections, substantially as described.

3. The combination with a heating fun nace having a smoke outlet at itsupper end, of an exteriorcasing enclosing sald furnace and suitablyspaced from the walls thereof;

tion between suchsections; a pipe leading to V the chimney communicatingwith oneof said sect1ons; and doors closing the said space or chamber,substantially as descrlbed.
